Javascript: If Else

This entry is part 15 of 27 in the series Javascript Tutorial

The If…Else… statement in Javascript is similar to other programming languages such as C.

It will first check if a condition is true and will execute a block of code if the condition is met.

<!DOCTYPE html>
 <title>If Else</title>
 function myFunction() {
   var passing_score = 60;
   var your_score = 70;
   if (your_score > passing_score) {
      document.getElementById("str1").innerHTML = "You have passed";
      } else {
      document.getElementById("str1").innerHTML = "You failed";
  <p id="str1">Passed or failed</p>
  <button onclick="myFunction()">Click Me</button>


As your_score, which is 70 is greater than passing_score which is 60, the first condition is output in the browser.

In the fiddle, you can try changing the value for passing_score or your_score to see what is output in the browser.
